ok my 1989 240SX with a KA24E its been sitting for about a month and i started it up and the engine its self was smoking alot and shaking alot like a mount was loose. Then after it warmed up it stoped so i went to the gas station and put some gas in it. Then when i got back home the coolent was boiling and after it cooled down the hole contatner was black anyone know whats wrong? HELP!! and it sounding like some of the cylnders were not firing

 

****ed headgasket?

 

yea another reason to put the new KA in becuase it already has a blown piston ring
